Modern Chess, Opening Databases, September 8, 2021.
We are happy to present the newest opening research by GM Pavel Eljanov. This time, he provides a complete repertoire for Black after 1.d4 d5 2.c4 e6 3.Nc3 c5 Actually, the idea of the database is not to provide another Tarrasch repertoire. The cornerstone of the current survey is the position arising after 4.cxd5 cxd4!? For a long period of time, this gambit line was considered to be quite dubious. Recently, however, Grischuk found improvements for Black, thus bringing the entire concept back to life. The tests on the highest level proved that the variation is completely playable. Of course, in order to provide you with a complete solution, Eljanov examines White's main alternatives on move 4 - 4.e3 and 4.Nf3.
